Atipik Eritema Multiforme ile Komplike Olmuş Bir Orf Olgusu

Abstract

Human orf is a viral zoonotic infection caused by a parapoxvirus. Parapoxviruses are a genus of Poxvirus family that infect different species of wild and domestic animals which may serve as reservoirs for human infections. Human parapoxvirus infections are almost invariably arise as a result of occupational exposure. Farmers, veterinarians, butchers are at greatest risk for acquiring infections through contact with an infected animal or an animal product. Although orf is a self-limited disease most commonly resolves spontaneously within weeks, atypical presentations and complications of orf are well known. Here we report a case of human orf who had been presented with atypical targetoid lesions of erythema multiforme. After clinical and histopathological investigations a diagnosis of human orf complicated with atypical erythema multiforme was made. The patient was given symptomatic treatment in conjunction with single dose of prednisolone and within weeks all of the lesions almost completely resolved. Through the presentation of this case report we wanted to emphasize a rare complication of orf.
